An automatic adjustment table for contour measurement

Abstract

This invention discloses an automatic adjustment stage for contour measurement, relating to the field of measurement technology. The automatic adjustment stage for contour measurement includes guide bars that mate with the straight grooves on the table of a scanning profilometer. By automatically controlling the motors in the Y, XOY, and XOZ directions and through programming, the automatic adjustment stage can achieve automatic calibration of the parallelism between the positioning grooves on the stage and the sensor's movement direction, and automatic positioning of the highest point of the generatrix of a rotating part. This eliminates accuracy errors caused by manual adjustment and improves efficiency. The Y, XOY, and XOZ directions each have corresponding adjustment components, all driven by linear servo motors. By controlling the extension and retraction of the motor shafts, and with the cooperation of the transmission reference and clamping mechanism within the components, precise movement in different directions and at different speeds can be achieved, thereby realizing precise positioning of the measured part.

Description

Technical Field

[0001] The invention relates to the field of measurement technology, in particular to an automatic adjustment workbench for contour measurement. Background Art

[0002] The machinery industry has achieved 0.001μm feeding technology and 0.005μm machining accuracy, requiring detection technology to adapt to it. With the improvement of domestic machinery manufacturing technology, in order to more accurately measure the surface morphology of product parts and verify whether product manufacturing meets the design requirements, high-precision contour and roughness measuring instruments using scanning measurement methods have become popular. In the process of measuring the surface of the product by scanning, when the instrument performs targeted measurement on specific parts of the product, it is necessary to place the product on a precise and efficient workbench and adjust the position and angle of the product. At the same time, when measuring the same product in batches, it is necessary to quickly locate and accurately measure it to meet the growing needs of precision production and measurement.

[0003] At present, there are two types of adjustment tables used in contour measuring instruments on the domestic and foreign markets: electric automatic adjustment and manual adjustment.
